JOINT-CHAIR.

Specification of Letters Patent.

Patented Deo. 13, 1910.

Application filed January 14, 1910. Serial No. 538,069.

organization of elements for effectively holding the meeting ends of railwa)v rails oy cstablishing an under Support as well as a loclt therefor whereby the lateral movement.- of the rails is entirely ohviated and the longitudinal movement ot the rails effectively limited.

lfith the above, and other objects in view, which will appear as the description progresses, the invention resides in the novel construction and arrangement of parts hereinafter fully described and claimed.

In the accompanying drawings there has been illustrated a 'simple and preferred embodimentof the improvement, and. in which drawings,

Figure l is a perspective view of a joint chair constructed in accordance with the present invention. Fig. 2 is a transverse sectional view ot' the same. Fig. 3 is a perspective view ot' the spacing bleek. Fig. 4 is a side elevation of the rails, parts being shown in section, and one of the members comprising the joint chair being removed. F 1g. 5 is a perspective view of one of the locking dogs.

In the accompanying drawings the numeral l designates the meeting ends of a pair ot rails. These rails l are of the ordinary construction comprising heads Q, webs 3 and base flanges 4.

The numerals 5 and 6 designate a pair of members comprising the joint chair. These members 5 and 6 comprise metallic blocks provided with a cut awa)Y portion adjacent their inner faces. This eut away portion comprises a substantially horizontal wall 7 and an inclined wall 8 terminating with the face of the said blocks 5 and 6. The walls provided by this cut away portion are adapted to coincide with the shape. of thce base flanges 4 of the rail members l., so as to provide a secure pocket for the said 'base flanges. The portions of tne blocks below the hor zontal walls 7 are provided with a plurality of longitudinally extending openings 9, the same being adapted for the reception ot threaded headed bolts l0 which are provided with the usual nuts l1. Positioned between the members 5 and 6 is a spacing block lr?, the saine being constructed preferably of wood and being also provided with a plurality of openings 13 registering with the openings 9 of the members 5 and G. The base flange 4 ot the rail members l and 2 is centrally provided adjacent its ends with a substantially V-shaped pocket; 1l, and adapted to he positioned within this pocket is a.V

V-shaped locking dog 1:. The horizontal wall 7 of the cut away rei-tion of the members 5 and (3 is provided with rectangular openings 1G registering with the openings let of the rails and adapted for the reception of the lockingdogs l5.

From the above description, taken in connection with the accompanying drawings, it will be noted that I have provided a simple and eli'cctive joint chair for connecting the meeting ends of a pair of rails, one which, through the medium of the spacing block 1:2 may be arranged to tit the base flanges of rails of various widths, one which can he readily adjusted so as to tightly ein gage with the base flanges of the rails, and one which through the medium of the loosel positioned locking log l5 eifect'ively prevents the longitudinal movement ot the rails.

It will be noted, by reference to the several figures of the drawing, that the members and t3 have their central portions adjacent their inner faces provided with npstanding oll'set members A. the same having their horizontal edges underiviug the ball of the rail members l. Each olllset A is provided with a pair of spaced openings, the same being adapted to aline with similar openings in the webs 3 of the rails l adjacent. their meeting faces, and these openings are also adapted for the reception of suitable retaining elements designated b v the letter B. B v this arrangement, it, will be noted that sinking of the rails at their point of meeting is entirely obviated and that the said offsets A add great strength to the structure.

Having thus described the invention, what.

I claim as new is 1. In a device of the class set forth, the

combination with the meeting ends of a pair 110 Y Inv of rails, said, rails havins their base flange? in the pockets, of the rails and adapted to en-V gnge the rece ses 'of the splice nisnihers, :i spacing block between the meeting faces of the splice members, and transverselv extending .securingr elements for the members of the joint chair and the Spacing block.

:2. In a device of the clash Qet forth, the combination with rail sections, ot' a lfoint chair for the raila` Said joint chair comprising' a pair of memherS, each having longi- Q indinal cnt away portions :adapted for the reception of the base flanges of the rails, the members heiner fin-ther provided with vertical oll'sets adapted to underlie the liall of the rails, meansfor connecting these otl'sets with the webs ot' the rails, the hase flanges of the rails being provided with spaced subtantiall-v V-shapcd pockets, V-shaped blocks czirri ld h v the members comprising the joint chair and adapted to engage the pockets of the mil, a spacing block bet-Ween the said splice members, and means for connecting the aplice. members helmv their points of engagement vrith the haSe flanges ot' the rails.

In testimony whereof I atiix my signature in presence of two witnesses.
